Touch sensations and proprioception are carried primarily along the:
a. spinocerebellar tract
b. dorsal column system
c. spinothalamic tract
d. spinoreticular tract

b. dorsal column system  

Explanation:

The backbone system is responsible for the sensation of touch and proprioception (which is the ability to recognize the spatial location of the body, its position and orientation, the force exerted by the muscles and the position of each body part relative to the others).

This system transmits information outside the body to a region called the postcentral gyrus in the cerebral cortex, which transmits stimuli, sensed by the body, to the brain.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

the eggs of the insects should be the first thing collected at the scene.
